Troubleshoot counterfeit detection errors on TD Terminals. Analyze possible causes and solutions. Ensure safe handling in retail environments.
Movement may indicate cable damage or power supply disruption.
Extreme temperatures and humidity can affect sensor performance.
Identify potential sources of EMI.
Counterfeit detection typically relies on a combination of hardware and software analysis. Hardware sensors measure optical properties, magnetic signatures, and bill dimensions. Software algorithms analyze the sensor data against known patterns. Failure can arise from sensor malfunction, signal attenuation, corrupted software, or database errors. Erroneous readings due to ESD events can also trigger false positives. Signal integrity over serial communication lines (baud-rate) could also contribute.

Electrical Hazard: Always unplug the terminal before inspecting or cleaning. Do not use liquids to clean the device. Risk of data loss if the terminal is abruptly powered off during a transaction. ESD Hazard: Static electricity can damage the terminal's internal components. Ground yourself before touching the terminal, especially during dry weather. NEVER open the terminal; doing so will trigger anti-tamper mechanisms and void any warranty.
Regularly inspect terminal cables for strain or damage. Ensure the terminal is placed in a location free from excessive dust or moisture. Clean the terminal's exterior surfaces with a dry, lint-free cloth. Implement a schedule for software updates. During winter months, take extra care to minimize static electricity near the terminal.
Try running the terminal's built-in diagnostic tools (if available) to check the sensor's health. Consult the terminal's manual for instructions on accessing the diagnostic menu. A 'factory reset' (if supported) may resolve software corruption issues, but note that this will erase all custom settings. Be sure to record any specific error codes before contacting support.
